Currently, diff_index passes the full relative path from the
repository root to the callback. In case of an addition, it passes
the tree entry instead of the index entry.

This change fixes the path used for addition, and it passes only
the basename of the path. This mimics the current behavior of
git_tree_diff.

For the diff-index tests, the diff_more test will run multiple
times. Reset the expect_idx counter after each test in order to
allow this.

The git.git implementation allows this, and there is no reason not
to.

The clay test suite files clay.h and clay_main.c are generated by
the clay python script. Teach CMake about this dependency and
remove the generated files from the repository.

Added link to vala bindings

Add Perl to the list of bindings.

Includes relevant Clay test

Small enhancements to remote-ls when working against local repositories

remote: add test to retrieve the advertised references from a local repository and fix related implementation

config_file: honor error

Return an error if we can't write an updated version of the config file
after config_delete.

Along with that, fix an uninitialized warning.

In an effort to remove duplicate code, I accidentally left
the stat structure uninitialized in this function.  This
patch restores that data gathering.

Really delete variables

Instead of just setting the value to NULL, which gives unwanted
results when asking for that variable after deleting it, delete the
variable from the list and re-write the file.

This would make us think that config variables like

    [core]
        something

is missing.

Comes with support for global events; this fixes #496.

It was not safe for git_buf_joinpath to be used with a pointer
into the buf itself because a reallocation could invalidate
the input parameter that pointed into the buffer.  This patch
makes it safe to self join, at least for the leading input to
the join, which is the common "append" case for self joins.

Also added unit tests to explicitly cover this case.

This should actually fix #511

This commit fixes #511.

This converts virtually all of the places that allocate GIT_PATH_MAX
buffers on the stack for manipulating paths to use git_buf objects
instead.  The patch is pretty careful not to touch the public API
for libgit2, so there are a few places that still use GIT_PATH_MAX.

This extends and changes some details of the git_buf implementation
to add a couple of extra functions and to make error handling easier.

This includes serious alterations to all the path.c functions, and
several of the fileops.c ones, too.  Also, there are a number of new
functions that parallel existing ones except that use a git_buf
instead of a stack-based buffer (such as git_config_find_global_r
that exists alongsize git_config_find_global).

This also modifies the win32 version of p_realpath to allocate whatever
buffer size is needed to accommodate the realpath instead of hardcoding
a GIT_PATH_MAX limit, but that change needs to be tested still.

For each difference in the trees, the callback gets called with the
relevant information so the user can fill in their own data
structures.
